A man who claims he was drugged, sexually assaulted, and filmed by a group of men in a gay bathhouse on Capitol Hill last summer has filed a lawsuit against one of his accused assailants. The case spilled out of the courts over the past year with a series of “wanted” posters documenting allegations against the alleged attacker that have appeared on Capitol Hill utility poles.

In his lawsuit, Robert Isacson says he sustained unspecified injuries in the July 2013 attack inside Summit Ave’s Steamworks and said he is concerned the accused will publish videos of the incident.

In an April countersuit denying the accusations, the defendant said Isacson put up the “wanted” posters around Capitol Hill and online with the defendant’s name and photograph. The defendant, 37 and a Tacoma-area resident, is seeking at least $1 million in damages. CHS is not naming the man because he has not been charged with a crime.

Attorneys for Isacson countered the defamation claims in a response last week citing First Amendment privileges and said that the posters were made with “the proper motive of informing the public.”

Isacson’s attorney declined to comment for this story as did a Steamworks representative. A representative for that firm said she was unsure if police had investigated the alleged incident. The defendant’s attorney did not return a call for comment.
